Magnetic field dependence of the carrier's effective mass and the g-factor in graphene

ORAL

Abstract

It has been established that the intrinsic Zeeman energy is one half of the cyclotron energy for ``\emph{bare}'' electrons in graphene. Consequently, there could be Landau-level mixing between the energy bands. We investigate how the band mixing is affected by the Coulomb interaction. Pairing of the electrons and holes in the presence of a circularly polarized light is also considered for several filling factors. We calculate the quasiparticle effective mass and effective $g$-factor for dressed electrons and holes in monolayer graphene. As an intermediate step of these calculations, we obtain the dielectric function for the case of electron dressed states and investigate how the magetoplasmons modes are affected by the electron-photon interaction.
